CARLI 4.5"-5.5" LIFT PROGRESSIVE RATE COILS 2005-2023 FORD SUPER DUTY 4X4

Carli's Multi-Rate coil springs are built with a custom wind, giving them a progressive variable rate. This design delivers smooth initial compression feel on highway chatter and small bumps as well as smooth rate transition to higher rates as the suspension cycles deeper into the travel. On 2005-2019 trucks, these coils will provide 4.5" of lift on diesel trucks. These are not designed to work on gas engine trucks and will fit far above the advertised lift height if attempted on a gas truck. For 2020+ trucks, these coils will provide 5.5" of lift on a diesel equipped truck.
